JOHN WALTER GRIFFIN, OF TORONTO, ONTARIO, CANADA.

BABY-CARRIAGE.

PECIFICATION forming part of Letters Patent No. 334.372, dated January12 1886.

- Application filed October 1, 1885. Serial No. 178,744.

To all whom it may concern:

Be it known that I, JOHN WALTER GRIFFIN, of the city of Toronto, in thecounty of York, in the Province of Ontario, Canada, accountant, haveinvented certain new and useful Im- I from the handle; and it consists,essentially,

of brakeshoes connected to a crank-rod journaled on the frame of thecarriage, and provided with a suitable rod extending to the handle ofthe carriage, the whole being arranged substantially as hereinafter moreparticularly explained.

Figure l is a perspective view of a babycarriage provided with myimproved brake. Fig. 2 is an enlarged perspective view of thebrake-gear.

In the drawings like letters of reference indicate corresponding partsin each figure; but before describing the construction of the apparatusI will draw attention to the necessity for a brake of the kind.

It is well known that accidents frequently occur through babycarriagesbeing unattended on an incline, which causes the carriage torun away, asit were, and in some instances that I know of the lives of children havebeen lost through that cause. By the adoption of my invention it wouldbe impossible that an accident of the kind I mention should occur, asthe mere movement of the carriage instantly applies the brake andarrests its motion.

It will be seen by the drawings that the brake-shoes A are connected bythe armsB to the crank-rod O, which is journaled, as indi (No model.)Patented in Canada October 10, 1885, No. 22,621.

cated, on the frame of the carriage. D is a rod connected to thecrank-rod O, as shown, and extending up to the handle E, as indicated.

A cross -T, F, is connected to the end of the rod D, and is shaped sothat when pressed against the handle E it will be held in positiou. Whenthe party in charge of the carriage takes hold of the handle E, she atthe same time grasps the cross-T F, holding it against the handle E.This action pushes down the crank of the rod 0, imparting acorresponding upward movement to the arms B, and these arms are of sucha length and so located that their upward movement carries theshoesAclear of the wheel G. When the party pushing the carriage lets goof the handle E and cross-T F, the weight of the shoes A are sufficientto cause them to drop down against the rim of the wheel G, and if thewheels move forward their motion will cause the shoes A to grip theirrims more tightly, thus effecting the brake desired.

In Fig. 2the full lines Show the brake-shoes applied, while the dottedlines show them elevated, so that the operation of my device will beclearly understood by reference to the said figure.

- I have shown two brake-shoes; but of course it will be understood thatone may be found sufficient.

What I claim as my invention is A brake'shoe, A, connected to thecrankrod 0, journaled on the frame of the carriage, as indicated, incombination with the rod D, connected to the crank-rod O,- and providedwith a cross -T, F, arranged substantially as and for the purposespecified.
